Complexity & Distraction in LBP

Relationship Between Complexity and Pain in a Walking Task With Distraction in the Chronic Low Back Pain Patient by Fractal Analysis: Pilot Study

Motor control, notably expressed through the complexity of the variability of the locomotor pattern, is disturbed at the central level by an apprehension of pain and movement, more than pain itself (or by biomechanical / structural damage of the spine) in chronic low back pain (cLBP) patients.

The aim of this study is to control that variability is reduced during gait at comfortable level and to test that distraction can reduce pain avoidance and therefore increase variability in cLBP patients.

Inclusion Criteria:

• The patient must have his informed consent and signed the consent form.
• The patient must be affiliated or beneficiary of a health insurance plan
• The patient is at least 18 years old and under 75 years old
• Patients with common chronic low back pain for more than 6 months

Exclusion Criteria:

• The subject participates in another interventional study
• The subject is in an exclusion period determined by a previous study
• The subject is under the protection of justice, guardianship or curatorship
• The subject refuses to sign the consent
• It is impossible to inform the subject
• Chronic symptomatic low back pain (tumoral pathology, infectious, or progressive inflammatory)
• Unable to walk for more than 10 minutes (during interrogation)
• Lower limb pain (EVA lower limb (s) ≥ Lumbar EVA)
